TIE PLATE.

1.11.1 ,eze.

' :Atpiicafian area May 31,

An objectof my inventionis to prevent creeping of the rail longitudinally of the track. h

Another object of my invention is to provide a structure inwhich the spikes holding the rail always remain tight contact with the rail flange and never protrudewhen weight is placed on the rail. p 7 A still further object of my invention is to enable part ofthe load on the rail to be borne by the spikes themselves, whereby part of the load on the upper surface of the "tie is relieved, and the life of the Wooden tieis prolonged. I V H'eretofore, in ordinary railroad constructime after the ties had been in place for a short period of time the weight of the pass ing traflic caused the railsto become embeddedin the upper surface of the tie and the spikes to protrude above the railflange,

In my rail holding 'deviceunder the'rail flange aiidrestinq' upon the top of the tie I providea tie plate which has spike apertures therein. Adjacent the spike apertures are spike lugs adapted after the s )ikes are driven into place intc'the tie tobe bent down and rest uponthe headoit thespike, thus insuring-that any pressure on the plate will be tI-flllSlIllttQCltO the spike. Rail holding lugs are also upstruckon the tie plate to i hold the rail from slipping laterally of the track in one direction. Grip jaws'prevent the creepingof the rail.

lVith these and other objects in view which may be incident to my improvements,

the invention consists in" the parts and com-r binations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention may be varied inconstruction, proportions and arrangements, without. depart-- ing from the spirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying fip ecification of Letters Patent.

the sameinto practical eflect, without limiting the improvements in their useful applicat ions to the particular constructions, which tor the-purpose ofexplanation, have been made the subject of illustration.

In the drawings:

Figure 1 is a topplan view of my device as ap'plied to a railroad rail.

Fig. 2 is an end elevation of iny device. '1 3 is a side elevation of my device.

F 1g.- 1 is a detail of the grip jaw.

Fig. 5 is a cross section of my device taken on the line 55 of Fig. 1' and showingtlie position of the spike lugs after the tie plate is in position.

In the drawings, I have shown a wooden railroad tie 1 upon which restsmy tie plate 2. Bearing onthe upper surface of the" tie plate 2 are flanges 3 and 4; or a railroad 'rail,

There are rail holding rip-struck lugs 6 formed on one endrof the tie plate 2' and adapted to bear against the flange 3 of the rail 5. These lugs are struck up from the body of the metal of the tie plate itself. 1

On one endof the tie plate 2 is provided a spike aperture 7 and ad acent the spike aperture is an upstanding spike lug 8. On"

theother end of the tie plate are spike apertp're's 9 and 11 respectively, and adjacent tiese lugs 12 and 13, respectively. Adjacent the spike aperture 7 is an aperture 1 1 in the tie plate within whichis adapted to fit a grip jaw 15. A lower gripping surface 16 of the grip jaw 15 is formed of metal of the same thickness as the tie plate 1 and fits under the flange 3 oi? the rail 5. An upper gripping surface 17 is formed so that it will contact and bear against the upper surface of the rail flange 3. The upper gripping element or surface 17 i of greater width than the aperture 14 in the tieplateand forms shoulders '18 which bear against the upper part of the tie plate when the grip aw is in position. Arecess 19 passing through the bend betweeuthe upper gripping-surface 17 and the lower gripping surface16 is formed of such shape, tliat a spike 21 driven into the tie will-have it head rest within the aperture 19 and bear against the upper grippingspike apertures are upstanding spike" apertures 9 and 11 respectively, and to grip the rail flange 4.

In adjusting the rail 5 on the tie 1 the plate 2 is placed in position with the .rail holding lugs 6 bearing against the flange 3 of therail. The grip jaw 15 is in position within the aperture 14 in the plate; the spike 21 is driven down in place which forces the grip jaw to slide in a direction towards the center of the rail base. This causes the upper and lower gripping surfaces 1'? and 16 res ectively to n. pinch the flange 3 tightly, and the spike21 holds the grip jaw in its wedged position. Spikes 22 and 23 have been driven in place and therail is now firmlynheld. Now, spike lug 8 is knocked down in the position shown in dotted lines in Fig. .5 and bears a ainst the top of the s ike 21. Lugs 12 an 13 respectively, are li ewise bent down by hammer blow or otherwise to contact with the heads of spikes 22 and 23 respectively.

The.,pressure of traflic on the rail 5 is I transmitted to the tie plate 2 and this through the bent down spike lugs 8, 12 and 1 3 is transmitted'to the spikes 21, 22 and 23 respectively, thus minimizing the pressure of the tie plate against the tie 1. i There can of the rail 5 longi beno, ossible creeping of th y'reason e grip tudina ly of the track jawwhich firmly. holdsthe flange 3 because ofthenatural spring of the metal of which the grip 1 jaw 15 is constructed. The fe of a railroad tie employing my form of tie plate will be much longer than is customary and since the creeping of-rails iseifectually prevented the up keep of a systemiemploying my device is comparatively sm y y a While I have shown and described the preferred embodiment of my invention, I

wish it to be understood that I do not con fine myself to the precise details of construction herein set forth, by way of nine tration, as it is apparent that many modifications and variation may be made therein, bythose skilled in the art, without departi ing from the spirit of the invention, or ex.

ceeding the scope of the appended claims.

I claim as my invention:
